EDWIN C. WOR-NS, OF RUTHERFORD, NEW JERSEY.

LIQUID-TRAP.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed February 23, 1910. Serial No. 545,448.

T 0 all whom it may concern:

Be it known that I, EDWIN C. oans, a citizen of the United States, and resident of Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Liquid- Traps, of which the following is a specification.

My invention relates to devices for catching the waste water and refuse discharged by the waste pipe of ice boxes or refrigerators, and the object is to provide a device of said character which will be simple in construction, effective as a trap, quickly applied and easily kept clean.

Referring to the drawingsFigure 1 is a sectional elevation of my device taken on line m Fig. 2. Fig. 2 is a plan view of the device. Fig. 3 is a plan showing the cap removed. Fig. 4 is an inverted view of the cap, detached, part of the lower wall of the annular groove thereof broken away. Fig.

is a side view of the cap, detached.

2 is the basin made of metal and preferably circular in shape. The interior of the bottom 3 of the basin has cast to it the circular upright portion 4 and through which is a central opening 5. Into this opening 5 is placed the waste pipe 6 for carrying off the waste water from the basin and trap. The upper edge of the pipe 6 is on. a line with the top edge of the upright 4 and in order to hold the pipe 6 to the upright I cliainfer or bevel off the upper edge 7 of said upright outwardly, and into the space 8 formed between the chamfered end of upright 4 and the waste pipe 6 force solder which will create a perfect and tight joint not liable to leak, but which can be readily unloosened when a separation of the parts is necessary. On the outside of the circular upright 4 there are formed a plurality of ears or projections 10 see Figs. 1 and 3, Over the circular upright 4 of the basin is placed the detachable circular cap 12 provided with a central core portion 13 cast integral-therewith. This core extends downwardly within the cap, see Fig. 1, slightly below the same where it is closed. A tapering cir cular cavity is formed within the core 13 extending downward to nearly the bottom of the same. The interior circumference of the cap is provided with an annular groove 15 the lower wall 15 thereof being pierced with openings 16. At or near the lower edge 17 of the cap, and around the circumference of the same the shell of the cap is cut with a plurality of holes 18, each leading into a vertical slot 19 of less width than the diameter of said holes. The basin is set into the floor or into a separate piece which can be fastened in any suitable man ner to the floor.

The tube or pipe 20 (in dotted lines) extending from the ice box 21 is inserted into the opening 14 see Fig. 1. As the waste water from the ice box fiows down this tube it will fill up the opening 14, and when completely filled will fiow over the top and down the sides of the cap 12, into the lower cavity 3 of the basin, filling same on the outside of cap and also on the inside by passing through the holes 18 and slots 19, thereof, to a level with the top of the upright 4 and waste pipe, where the said water will overflow same and down said waste pipe. The bottom or well 22 of the opening 14 below and above the tube 20 being always filled with water will act as a trap for sealing the mouth of the said tube 20 for preventing air or sewer gas entering said tube and into the ice box. The water in the lower portion 3 of the basin also serves as a trap against sewer gas.

The narrow slots 19 of the cap serve to prevent match-sticks and the like passing into the cap and into the waste pipe.

The circular cap 12 is made detachable in order that it may be easily removed, for fastening the waste pipe to the basin and also for repairs. This cap is held against accidental displacement by the projections 10 on the basin upright 4, which are intended to enter the annular groove 15 in cap which is effected by first passing the projections 10 through the openings 16, and then turning the cap until said projections enter the groove 15 and thereby locking the said cap in place.

The shape of the outside 25 of the basin is made to prevent dirt, &c., getting under basin when resting on the floor.

\Vhat I claim is:

1. In a liquid trap, a detachable cap, a basin having a central upright having a central hole, said cap placed over said upright, said cap having a central core with a central tapered cavity, said cap provided with orifices and slots cut around its circumference, and means for securing said cap in position.

-2. In a liquid trap, a detachable cap, a basin With an integral upright having a central hole, said upright of said basin having one or more ears or projections, said cap placed over said basin-upright, said cap having an annular groove, the lower Wall of the same having one or more openings, adapted to allow the said ears to pass into the said annular groove, said groove adapted to engage said ears when said cap is turned, so as to lock said cap in place.

3. In a liquid trap, a detachable cap, a central core integral With said cap, said core having a central tapered cavity, said cavity serving as a trap for the purpose described.

Signed at New York in the county of New York and State of New York this 28th day of January A. D. 1910.
